Public Act  215 of 2009, effective January 4, 2010, amends Section 7 (MCL 125.2307) of the Mobile Home Commission Act by adding a subsection 7 that allows local governments to inspect mobile homes for safety whether or not they are in a mobile home park when they are being rented to a tenant by the owner.  The act also allows local governments to propose a means to determine which mobile homes in its jurisdiction are being rented, including a registration or licensing requirement for renting a mobile home. 

To inspect a rented mobile home for safety, the locality’s safety inspection ordinance must apply to all other rental housing within its jurisdiction.  The interval between inspections cannot be less than 3 years, unless an inspection is done in response to a tenant complaint.  The enforcement standard for an inspection cannot exceed the relevant national standard (at 42 USC 5401-5426).  An “inspection for safety” is “limited to ensuring the proper functioning of, or protection, of” the furnace, water heater, electrical wiring, sanitation and plumbing, ventilation, hearing equipment, and structural integrity.
